Process-memory disclosure via image bounds over-read
Published Sep 6, 2023 · Updated Feb 13, 2025
Out-of-bounds read in Model I/O in Apple macOS before 13.3 allows local users to disclose process memory through a crafted image. The Model I/O image-processing path reads beyond validated input bounds when parsing attacker-controlled image data. Exploitation requires a user or application to process the image, and the documented consequence is limited to process-memory disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
